What is the onset time for IV administration of Ketamine?

The onset time for IV administration of Ketamine is approximately 30 seconds. When administered intravenously, Ketamine quickly enters the bloodstream and reaches the central nervous system, leading to its rapid analgesic and anesthetic effects. This quick action is particularly beneficial in tactical situations where the immediate control of pain or sedation is required.

The other onset times listed are slower than the actual onset of Ketamine when delivered intravenously, which could delay necessary treatment in situations that require prompt pain management. The swift effect of Ketamine makes it a valuable tool in tactical combat casualty care.
